Na. 0,6%, Patented Jany 1, 186% 4blocks xX xX, having journals at their lower ends which workin suitable bearings 1/X yX, on the platform or bed,

` These blocks, '.'rX xX, are connected by a spring or springs, a1/, and are parallel with the platform-or bed, and

they have the rear ends of two chains XX att-'achedto them, the chain of one' block extending over the shaft QX, and over the top of the other block and around a pulley 2X, andthen extending forward to the `front end of the shaft Q where it is attached, as shown ataXX. The chain of the other block has a similar but'reverse connection, as shown clearly in iig. 2. Each block xX is provided with pendent arms, YX, which extend. down nearly to the platform MX, as shown clearly in iig. 7, and the lower shaft, PX, has 'a pin, LXX, projecting Uip from it, the Y lower end of said pin being connected with a spring cXX, on shaft PX. The shaft QX, has a pin, cZXX, passing transversely through it, and the under side of the upper shaft QX, has an oblong slot, eXX, made in it, whichhas two indentations, fXX gXX, into which the pin bXX catches, (see iig. l.) When the pin bXX is in the indentations fXX-t-he pendentarms YX are distended or forced apart, as shown in iig. 7, and in this position they are shoved florward to the front edge of the platform MX, under the action of the lover RX, and when said arms have nearly reached the extent of their forward movement the spring cXX, tovwhich the pin XX is attached, cornes in contact with the front prong of the shaft OX, and Ais thereby actuated by the shai't PX so as to throw the pin `IJXX out of the indentationsgfXX, and-the arms YXimmediatcly close under the action of the springs al/ of the blocks zv, the upper shaft, QX, being forced back. under thc pull or draw of the chains XX, and the pin bXX catch- .ing into the indentation gXX. The arms YX, in closing, grasp the cnt grain on the p latform'andarc drawn back with the grain between them under the reversevmotion of the lever RX, until the latter nearly reaches the termi-4 nation of its backward movement when the shaft OX is turned, owing to its connection with thc lever RX, so Vas to move the arms YX with their load off from the platform, and the shaft PX being still shoved backward, the uppershaft, QX, being held by the pin cZXX theicha'ns XX open the arms YX, and the grain is discharged, and the armsarc held in an open state in consequence of the pin bXX catching into the indentation fXX, and are held open `while ibeingagain forced forward tc grasp the lcnt grain.

Having thus described my invention,i what I claim as new, and desire'to' secure 'by Letters Paten-t, is-

1. The arrangement of the collar D, with the'wheels E or F attached, or both the sliding parts a a ortheir equivalents of the clutches Gr G, and the spring H, or its equivalent, all placed on the axle C, to operate in connection with the pinions I orrJ or both, substantially `as and for the purpose set' forth.

2. The clutches Gr' G', L L and O O', when combined and arranged with sliding collars or sleeves, and with variable or diiferential gearing, substantially as and for the purpose specified.

3. The curved bar EX, in combination with the adjustable guide FX, arranged as shown for the purpose of 4elevating or depressing the front ends of the fingers or guards, as described.

.4. The arm KX, connected to the rear side of the curved bar EX as shown, in combination with the adjust* able guide FX connected with the bar EX, as shown, for the purpose specified.

5. The bar HX, connected to the upper side of the bar EX, by a hinge or ljoint 0X, and provided with Indiarubber spring d X, as shown, in combination with thgrrg-on the adjustable guide FX, substantially as and for `the purpose described. j 5

6. The grain-discharging deviceI composed of the two shafts PX QX, arms YX, arranged with the chains XX, and pulleys and operated automatically from the axle C or other suitable driving shaft, by the lever RX, pin XX, substantially in the manner as herein set forth. i
